goog.net.XhrManager.send() id

[John Munro]

What are you guys using for the id parameter of goog.net.XhrManager.send()?

For the short term I'm incrementing a number property on a parent class and converting it to a string, but eventually the number will overflow and in any case it doesn't need to be that unique - only unique among current requests.

Is there a standard solution or best practices for this?  I don't actually need the id for anything, since I'm not planning on aborting any requests.

I use the uri + increment.  JS numbers are floating points so dont worry about overflows, even if they were integers you would never really overflow (well that depends on #requests per seconds and the number of centuries you keep the browser open for).
